In this videos, I am explaining the answers of following 5 important questions from Genetics. Watch full video to learn more.
NEET QA series: Genetics -1
Q.No.1 A tobacco plant heterozygous for albinism ( a recessive character) is self pollinated and 1200 seeds are subsequently germinated. How many seedlings would have the parental genotype?
a) 1250 b) 600 c) 300 d) 2250
Q.No.2 Two pea plant is subjected to cross pollination and 183 plants produced in next generation. 94 plants were tall, 89 plants were dwarf. What are the parental genotype?
a) TT × TT b) Tt × TT c) TT × tt d) Tt × tt
Q.No.3 In a DNA strand no of H-bond is 700 with 10% Adenine. Find out the length of DNA-
a) 700Å b) 750 Å c) 800 Å d) 850 Å
Q.No.4 Resistance to a fungus in pea plant is conferred by gene ‘h’ which is completely recessive to its allele ‘H’ for susceptibility. If a resistant female plant is crossed with a homozygous susceptible male what would be the order of genotype in pistillate (female) parent, staminate (male) parent, male gametes and egg?
a) Hh; HH; H; h b) hh; Hh; h; h c) hh; HH; H; h d) Hh; HH; h; H
Q.No.5 Consider a monohybrid cross between a pure tall plant and a dwarf plant. In F2 generation of this cross 4000 seedlings were produced. How many seedlings will be dwarf?
a) 0 b) 1000 c) 2000 d) 3000
